Nobody Told Me About id

Nobody Told Me About id (or NTMAi) is a gameplay mod for the GZDoom source port, created by Can't Sleep. The mod brings elements of the gameplay and style of games built on the (such as Duke Nukem 3D, ', and ') to Doom. Work on the mod started in the summer of 2019 and the first version was released on February 8, 2020. It won one of the Gameplay Mod awards at the 2020 Cacowards. The mod was redone from scratch in 2023.

The name of the mod refers to the track of the same name from the Doom soundtrack composed by Robert Prince.

Content
NTMAi can be player with any of the Doom IWADs, i.e. The Ultimate Doom, Doom II, The Plutonia Experiment, or TNT: Evilution. It also has several bonus features when playing one of the following PWADs: AD MORTEM, Doom 64 for Doom II, Eviternity, MAYhem 2019, Scythe 2, or Valiant.

Custom weapons
Sprites for all weapons show that they are held in the right hand, instead of being placed in the center of the screen as in Doom.

The player can now kick monsters with their foot by pressing the dedicated button, much like Duke with his mighty foot.
 * Kick

The pistol now has a reload. It happens automatically every ten shots, or can be triggered by the player using the secondary fire button. This is also a reference to Duke Nukem 3D where the pistol automatically reloads every 12 shots.
 * Pistol

The player can now carry up to 20 hand grenades. They can be used by pressing the dedicated button. Grenades can bounce off walls, floors, and ceilings. They will either explode upon touching the player, monsters, or exploding barrels, or after touching the walls, floor, or ceiling three times.
 * Hand grenades

Custom items
When the player attempts to interact with something that requires a key, instead of immediately activating it, an animation is played showing the player using the corresponding keycard or skull key on the object.
